THOMAS SPENCER MILLER, OF SOUTH ORANGE, NEW JERSEY, AND JOSEPH H.DICKINSON, OF ATLANTA, GEORGIA.

Specification of Letters Patent.

Patented Feb. 11 1908.

Application filed October 18. 1902. Serial No. 127-788.

T 0 all whom it may concern:

Be it known that we, THOMAS SPENCER MILLER, a citizen of the UnitedStates, and a resident of South Orange, county of Essex, and State ofNew Jersey, and JosEPH H. DIOK- INSON, a citizen of the United States,and a resident of Atlanta, Fulton county, State of Georgia, haveinvented a new and useful Improvement in Hoisting and ConveyingApparatus,'of which the following is a specification.

Figure 1 is a side view of one form of our invention adapted for acableway. Fig. 2 is' a detail of the load-carriage drum or sheave forthe same. Fig. 3 is a side view of another form of our invention adaptedfor a cable- Way. Fig. 4 is a detail of the load-carriage drum or sheavefor the same. Fig. 5 is a side view of another form of apparatuscontaining our invention. Fig. 6 is a detail of the loadcarriage drum orsheave of the same. Fig. 7 is a side view of a form of our inventionadapted for a logging apparatus. Fig. 8 is a detail of the load carriagedrum or sheave for the same.

In all of said figures, the head-support is at A, the tail-support at B.

O is the cable or trackway.

D is the load-carriage.

E is the friction operated hoisting-ropedrum of the engine. a is thehoisting rope operated thereby.

c is the fall-rope which, in one form, is in-' tegral with the hoistingrope e, and in other forms separate therefrom.

F is the friction slack-pulling-rope-drum of the engine.

f is the slack-pulling-rope which in one form is integral with thehoisting rope and in other forms is separate therefrom.

G is the friction traction-ropedrum of the engine.

g is the traction-rope operated thereby which is shown as substantiallyendless, hav ing both ends fast to the load carriage.

1, 2, 3 and 4 are guide sheaves on the head-support. 5 and 6 areguide-sheaves on the tail support. 7 and 8, the load-carriage wheelsrunning on the cable or trackway. H, the load-carriage drum or sheavecomposed of a plurality of parts h, 72/ or h, 7L2, h.

In all the forms of construction shown, the hoisting rope e and theslack-pulling-rope f extend from the carriage to the head-support andthence to their respective drums at the engine. At the load carriage,they respectively engage, directly or indirectly, with theload-carriage-drum or sheave II in such a manner that when hauled inthey tend to turn said drum or sheave H in opposite directions. Therelative surface speed'of the engine drums E and F is substantiallyequal, in

case the outer ends of the ropes e and f are both fastened to said drumor sheave H; but if either or both of said ropes c or f form a wrappingengagement with said drum or sheave H, the engine will be soproportioned that the surface speed of the engine drum F will beslightly faster than that of the enginedrum E to insure against anyslack occurring in said rope e by reason of any slipping of said wrappedconnection.

In the construction shown in Fig. 1, the load-carriage sheave or drum His in three parts, h, h and 72, The traction-rope g is substantially anendless rope fastened to the frame of the load-carriage D so as to beadapted to hold it in any position or move it in either direction. Thefall rope c has its upper end fast to the middle drum part h upon whichit is coiled. Thehoisting-rope e is fast at one end to the engine-drumE, and at the other end to one of the drum parts 7?. Theslack-pulling-rope f is fast at one end to the drum-engine F and at theother end to an end drum part 7L2.

In the form shown in Figs. 3 and 4, the traction rope is the same asbefore, but the hoisting-rope e, and the fall rope c are integral witheach other, or one continuous rope, which makes a sufiicient number ofwraps around the drum portion h to avoid slipping thereon. Theslack-pulling-rope f is ,as before, secured at one end to its enginedrumF and at the other end to the drum portion 72. The drum H consists ofonly two parts.

In the form shown in Figs. 5 and 6, the traction rope is, as before; butthe hoistingrope e and slack-pulling-rope f are integral with each otherconstituting a single continuous rope fast at one end to the enginedrumE and at the other end to engine drum F and making a sufficient numberof turns around drum part h to prevent slipping thereon. The fall-rope eis separate and made fast to the drum part h In this form, also, thedrum H consists of only two parts.

The construction shown in Figs. 7 and 8 is substantially like that ofFigs. 1 and 2, so

far as concerns the drum H, and its connec tion with the hoisting-ropee, slack-pullingrope f and fallrope e. The traction-rope however, isfast at one end to the enginedrum G and extends thence over the headsheave 2 between the guide-sheaves 9 and 10 on the carriage D, betweenthe guide-sheaves 11 and 12 on the supplemental carriage D, around thetail-sheave 5, and is made fast to the supplemental carriage D. Asubstan tial continuation g of the traction-rope g connects thecarriages D, D. The carriage D is provided with the wheels 13 and 14running on the cable or trackway O. A guidesheave 15 is pendent from theframe of carrier D and over this sheave the fall-rope e is led from thedrum H so as to facilitate the handling of logs by the tongs 16 at thelower end of the fall-rope e.

Although we have shown the several p arts of the drum H as co-axial andas rigidly se cured together, we do not limit ourselves to this form ofconnection or location. We Will employ the term, drum members, toinclude broadly all variations of connection and relative position ofthe three drum parts.

In operating the constructions shown in Figs. 1, 3 and 5, as thetraction-rope g moves the carriage toward the tail support, the ropes cand f are paid out in unison; and as it is moved toward thehead-support, the ropes e and f are hauled in in unison. The fall may belowered by holding the tractionrope stationary and hauling in on theslackpulling-rope f, and paying out correspondingly the hoisting rope c.The load may be hoisted by holding the traction-rope stationary, haulingin on the hoisting-rope c and paying out on the slack-pulling-ropeSubstantially the same mode of operation exists in Fig. 7 excepting thatthe construction therein shown being for logging purposes, no

endless ropes are employed; the return run of the traction-rope from theload-carriage to the engine being omitted and the hauling in of theropes e and f in unison being depended upon for moving the load-carriagetoward the head Having thus fully described our invention,

we claim as new and desire to secure by Letters Patent:

1. In a conveying apparatus, in combination, a trackway, a travelingcarriage thereon, an outhaul traction rope having its outer free endconnected to the frame of the carriage, a plurality of traveling drumparts connected in axial alinement, two stationary drums, a ropeconnecting each of said stationary drums with one of said traveling drumparts to operate inversely, and a rope operated by one of said travelingdrum parts for connection with an object to be hauled.

2. In a conveying apparatus, in combination, a trackway, a loadcarriage, an outhaul traction rope having its outer free end connectedto the frame of the carriage, a drum containing a plurality of connectedparts on said carriage, a fall rope from said drum, hoisting and slackpulling ropes extending respectively from the top and bottom of saiddrum toward the end of the trackway.

3. In combination a traveling carriage em- -bracing a triplex travelingdrum, an outhaul traction rope having its outer free end connected tothe frame of the carriage, a rope 1 for connecting the middle partthereof with the object to be moved, two stationary drums, and ropesconnecting them with the outer parts respectively of said travelingdrum. I

4,. In combination, a triplex traveling drum, three stationary drums,ropes connecting two of them respectively with the outer parts of saidtraveling drum, a rope connecting the third drum with the frame of saidtraveling drum, and a rope connecting the middle part of said travelingdrum with the object to be moved.

In testimony whereof we have hereunto signed our names to thisspecification in the presence of two subscribing witnesses.
